Well had my 2021 for 10 days now. I have about a 12 mile commute. with about half on the expressway.
Wasn't sure about the CVT at first but after a few days I started to like it. It's fun to get it up to speed and then back off the pedal Then it settles down and just cruises along. I'm finding out where I drive it gets the best mileage at about 60mph.
Today's high was about 63mpg and the attached photo is after I got off the interstate
